Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of wiring maintenance equipment, and in particular to a communication audio wiring maintenance test device and a test method. Background Art
[0002] In the era of rapid development of information and communication, voice distribution (VDF) is widely used in various industries as a carrier of various wired telephone services and 64K analog signal services. They can be found in almost every weak current room and communication room.
[0003] Communication audio wiring operation and maintenance is the most frequent task for communication line operators. However, with the increasing use of audio wiring resources, the complexity and problems of operation and maintenance are gradually exposed.
[0004] The first is the problem of real-time updating and statistics of the audio wiring table. Due to the relocation or change of user telephones or other analog signal service terminals, it is necessary to adjust the connection relationship between the audio wiring on the internal line side and the audio wiring on the external line side, and update the wiring record table at the same time to facilitate subsequent continuous operation and maintenance. However, in actual operation and maintenance scenarios, there are often problems in which operation and maintenance personnel fail to update the table in real time, resulting in the need to re-sort the audio wiring in subsequent work, resulting in lengthy operation time.
[0005] Secondly, in the current communication audio wiring test, the VDF wiring connection point where the phone is connected to the audio wiring module is mostly a metal clip. The original wiring needs to be hooked out for measurement, which often causes the hooked audio wiring head to be damaged and cannot be used anymore.
[0006] Finally, although the workload of audio wiring inspection and maintenance is not large, the tools involved are very fragmented, and maintenance personnel often forget to bring tools. Some tools also have problems such as unreasonable human-computer interaction design (for example, the test phone can only be held in hand, but during the maintenance process, personnel still need to use both hands to work; some test phones with hands-free function have spiral test lines that are not long enough, so the phone cannot be put on the ground and still needs to be held in hand; the spiral line has elastic force and often pulls down the contacts that are in good contact with the audio wiring, etc.) This causes the maintenance personnel to be in a hurry on site, and they often have to carry extra audio cables as extension cables for temporary remedial work before they can work. Summary of the invention
[0007] The purpose of the present invention is to solve the shortcomings of the prior art and propose a communication audio wiring maintenance test device and test method, which records the process in the maintenance operation to form a closed loop, improves the portability and integration of the device, and makes it more convenient for operation and maintenance personnel to use.

[0059] In order to more clearly illustrate the specific implementation mode of the present invention, an embodiment is provided below:
[0060] Before the present invention is implemented, the original wiring information needs to be imported into the information linkage control unit through the USB interface of the information input and output unit, and the information linkage control unit needs to be activated before it can be used normally.
[0061] A communication audio wiring maintenance test device and test method of the present invention include two debugging test methods for adding a new line and replacing an existing line, which are specifically as follows:
[0062] Working condition 1: Add a new phone number and a new wiring contact relationship;
[0063] S1. The operation and maintenance personnel bring the tool to the communication room, select the query function in the tool, enter the number to be added through the information input and output unit, query the internal line location of the number, enter the floor or room number of the newly added phone number, etc., and determine the external line location of the number.

[0066] S4. At this time, the tool module can be used normally. Lay the audio cable from the lower end of the corresponding number module on the inner line side of the audio patch panel to the upper end of the corresponding position module on the outer line side of the audio patch panel, and use the wire cutting piece to press the audio cables into the hanging grooves respectively.
[0067] S5. Dial the newly added number with a mobile phone. The corresponding office staff answers the call and confirms that the newly added number is successful. At this time, if N minutes have not arrived, the limit switch automatically locks the cutting piece of the tool module and waits for the next information confirmation before opening it.
[0068] Working condition 2: Personnel changes, change of office location of the number;
[0069] S1. The operation and maintenance personnel bring the tool to the communication room, select the query function in the tool, enter the number that needs to be changed through the information input and output unit, query the current internal and external positions of the number, enter the floor or room number to which the number needs to be moved, etc., and determine the external position to which the number needs to be changed.
[0070] S2.

[0071] S3. Enter the changed external line position information corresponding to the internal line position of this maintenance through the information update module of the information input and output unit selection tool, confirm and save, and the limit switch will be unlocked for N minutes according to the established procedure and locked again after N minutes.
[0072] S4. The tool module can be used normally. Use the cutting blade attached to the tool module to screw the original audio distribution module on the outside line side to the wire-releasing state, push out the hanging slot to hook out the audio cable, and after arranging it, insert it into the cable fixing hole of the audio distribution module on the outside line side that needs to be changed, and use the cutting blade attached to the tool to screw the original audio distribution module on the outside line side to the contact state.
[0073] S5. Dial the newly added number with a mobile phone. The corresponding office staff answers the call and confirms that the newly added number is successful. At this time, if N minutes have not arrived, the limit switch automatically locks the cutting piece of the tool module and waits for the next information confirmation before opening it.
[0074] It should be noted that in the existing machine room, VDF wiring is connected to different types of VDF unit modules, and the present invention can effectively solve the problems of cluttered tools and untimely and chaotic updating of VDF wiring information when cutting the VDF wiring for replacement and connecting another VDF unit module.
[0075] Example 2 (such as Figure 5 and Figure 6 shown):
[0076] The wire cutter and reset spring in the telescopic chute are replaced with the wire cutter 13 and the pull rope 12 in the prior art, and a limit motor is fixed at the root of the telescopic chute. The power output end of the limit motor is wound around the pull rope and provides the pull rope with the power to retract and release. The wire cutter is hung inside the telescopic chute through the pull rope, and the telescopic chute is blocked by the limit switch. When in use, the information entry and update are still required first, and then the limit switch is opened for a certain period of time. The wire cutter can be manually taken out for wire punching, hooking and wire cutting. After the wiring is completed, the wire cutter is placed inside the telescopic chute to reset. If the opening time is exceeded, the limit motor will rotate and pull the wire cutter 13 into the telescopic slot, so that the functional components of the wire cutter are not exposed, waiting for the second unlocking, to prevent people from forgetting to retract it after each work.
[0077] It should be noted that in the existing machine room, VDF wiring needs to be installed or removed on different types of VDF unit modules, and the core technical problem solved by the present invention is that it can effectively solve the problem of information update and wire punching, wire hooking and wire cutting processing being out of sync, and integrate the information update tool with the wire processing physical tool to achieve an organic linkage between the two, and use information update as a prerequisite for wire processing, thereby avoiding the problem of operators only performing physical wiring and ignoring information update, and thus avoiding the problem of confusion in the maintenance process caused by cluttered tools during installation or removal of blocks in VDF wiring related work and untimely updating of VDF wiring information.
[0078] Embodiment 3 (such as Figure 7 and Figure 8 shown):
[0079] In Example 1 (such as Figure 3 and Figure 4 ), the limit switch is replaced by an electromagnet switch-controlled locking structure, wherein the electromagnet includes an X-axis electromagnet 16 fixed at the root of the telescopic slide, and a Y-axis electromagnet 14 fixed at one side of the telescopic slide, wherein the X-axis electromagnet and the Y-axis electromagnet are both plugged with a coil rod 18, the coil rod of the X-axis electromagnet is slidably plugged into the tangent piece, and the coil rod of the Y-axis electromagnet is slidably plugged into the lock tongue 15; and a lock opening 17 for accommodating the lock tongue is opened on the side wall of the root of the tangent piece, and the Y-axis electromagnet embedded and fixed on the side wall of the telescopic slide in the Y direction provides the lock tongue with telescopic power, so as to realize the release and locking function after the tangent piece extends outward and retracts inward; and the X-axis electromagnet provides the tangent piece with X-direction retraction or ejection power.
[0080] In addition, it should be noted that the wire cutting piece and the wire cutting tool are both arranged in the telescopic slide groove. The present invention locks the wire punching, wire hooking and wire cutting functions through three embodiments of the wire cutting piece and the wire cutting tool. The limit switch is controlled by the information linkage control unit to perform the overall locking of the wire cutting piece and the wire cutting tool. The future technical improvement direction is expected to be the single function locking of wire punching, wire hooking and wire cutting, rather than locking the entire wire cutting piece, or setting the wire cutting piece outside the box body.
[0081] Finally, all the parts not described in the present invention adopt mature products and mature technical means in the prior art.
[0082] In the description of this specification, reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in the embodiment or example of the invention.
